sAsII CONSTRUCTION.

The present invention has to do with sheet metal sash, and isparticularly concerned with the construction o f the marginal stile andrail members. i

The princlpal object of the invention to provide', in a sheet metalsash, an improved marginal member= which is light, strong, narrow andextremely economical to manufacture.

Another fimportant object is to provide anv improved lock which isespeciallysu-itable for association with such a marginal memben Whilethe foregoing statements are indicative in a general way of the natureof the invention, other objects and advantages not herein specificallymentioned willbe apparent to those skilled in the art upon a fullcomprehension vof the 'improved' sash construction.

In order that the invention may be readily understood, one .embodimentof the same is presented in the' accompanying drawings and in thefollowing description, but it will be understood that such embodiment isintended merely for thepurpose of exempliication and is not to beconsidered as limiting the invention short of its true and intendedscope, as defined by the appended claims.4

In the drawings- Fig. 1 is a fragmentary side view` of a sash which isconstructed in accordance with the invention; r

Fig. 2 is a horizontal section through the sash, taken on the'line 2-2of Fig. 1;

i Fig. 3 is a vertical section, taken onthe Fig. 4 is a verticalsection, taken on the line 4-4 of Fig. 2; l Fig. 5 is a verticalsection,taken on the vline 5-5 of Fig. 1;-

Fig.y ,6 is a vertical section, taken on-the line 6-6 of Fig. 4;

,V Fi 7 is `a horizontal'se'ction, taken on the line -v-7 of Fig. 1; and

l Fig. 8 isa fragmentary perspective view of one ofthe stile members ofthe sash.

The marginal stile and 'rail members 10 and 11 ofthe sash illustrated inthe drawings are' of hollow sheet metal formation. Each 'of the marginalmembers consists of two U- shaped channel strips 12 and 13 which arearranged together in nested. relation, with the edges 14 of they innerstrip 13 bent reverselyabout and secured to the edges of the outer strip12, and with the back 15 of` the inner strip-'spaced a substantialdistance from Athe back 16 of the outer strip. The channel in the innerstrip 13 constitutes a groove for the reception of the usual glazingstrip l? and pane 18, while the channel in the outer strip 12, which isrelatively deep, is closed oii' by the back 15 of the iinner stripv andthat partA of it not occupied by the inner strip constitutes a space4for the reception of such hereinafter described elements as the cornerreinforcing members between the stile and rail members and the bolts ofthe locks 'associated with the sash.

Twolocks are advantageously ap lied to the two lower corners of the sash. ach of the locks includes an L-shaped housing 19, which opensagainst the sash and spans the joint therein between one of the sidestile members 10 and the bottom rail member 11. The housing 19 isprovided along its upper edge with a stationary lift piece 20. A,movable finger piece 21 is positioned at an inclination above and tothe, side of the lift' piece 20, and is pivoted at,'22 within thehousing 19. A spring 23 is secured within l the housing at one side ofthe finger piece 21, and bears resiliently -against a shoulder 24 on thesame, whereby to hold the finger piece normally in spaced relation tothe lift piece 20. The finger piece 21 is provided,

intermediate the pivoted and free ends thereof, with a laterallyprojecting pin 25 which extends through an opening 26 in onel of thesides of the' channel strip 12 of the lower rail 11, and engages againstthe sides of a4 above but in contact with the upper surface ofthe bolt,whereby to prevent the nose of:`

the same fromv yielding upwardly whenit comes into-engagement suddenlyand forcibly with a stop during downward movement ner reinforcing member30- at a point just of the sash.` The corner reinforcing :nem-v -ber 30,which is in the form of two laterally spaced and connected L-shapedplates, is positioned in the stilemember in closely fit- 5' tingengagement with the sides thereof by means of a. two-part telescopingscrew 34,

' Awhich. screw passes through the sides of the stile and reinforcingvmembers at a point where it is in contact with the upper edge nfof theblack sa The members@ is positioned in the rail member in simllarengagement therewith'by means of another twopart telescoping screw 35,which screw passes through not onlythe sidesof the rail 15' andreinforcing members but also through the lock housing 19. Ilhe-lockhousing 19 is secured against the side of the sash by means of the screw3 5 already described and two other screws 36 and 37 which pass Thespring 23 in the housing 19 normally holds the iingerpiece 21 in anelevated posi-.-

I on the same which abuts against one corner 'of the block' 33. Whilemany different forms of combined sash guides and lock racks may be used.in. association with the particular form of sash and Vlock herein dis'-vclosed, avery simple and eicient form of combined' guide and rack isshown iin the drawings.. It consists of a channel strip 39, 4to the backof which is attached, by riveting y or'welding, a number of sheet metalstampings 40, which stampingsare bent to'form horizontal stops 41 andinclined side-walls 42 for the stops. When the sash is being raised, thenose 31 of the bolt at each side" asjit passesupwardlyalong the inclineside-V ofthe sash will be cammed inwardl walls? 42 -of the stampings 39,and, when the sash has reached thedesired elevation and 1 isb'einglowered a little to lockgthe nose 31' will engage with one-of the stops241 and hold thevsash in that position the 'fmrggr piece 21 is depressed.
